TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent 1\`|0`l 598,653, dated February 8, 1898.

Application tiled March 22, 1897. Serial No. 628,610. (No model.)

in which means are provided for preventingv the type-bars or other type-bearing devices from reaching the paper on the platen at the end of the carriage travel or at the end of a predetermined line, whereby the printing of one character over another may be avoided;

and one of the objects of my invention is to provide simple and effective means of this character.

Another object of my invention is to provide a construction by which after the printing mechanism has once been locked it may be unlocked for the printing of additional characters, and also a construction whereby after such unlocking the printing mechanism mayagain be automatically relocked.

In carrying out my improvements I em` ploy the carriage-mainspring drum, case, scroll, or the like, or some part having a rotation in unison therewith to actuate the linelocking devices, and consequently when the printing mechanism (including the escapement mechanism) is locked or obstructed the said spring drum, case, dto., is simultaneously locked or arrested. If a short line be provided for and the carriage-release key be operated, when the carriage in its -unrestrained movement runs to the end ofthe predetermined line the drum would be automatically locked without the provision of some automatic releasing means therefor, and the strap, band, or belt connecting the drum and the carriage would bulge from or leave the drum and be liable to break or otherwise cause trouble.

Another object of my invention, therefore, is to provide means for automatically releasing the spring-drum and also, if desired, the line-locking mechanism when the carriagereleasc key is operated and the carriage is permitted to run down swiftly to or past the predetermined locking-point.

My invention consists inl the features of construction and combinations `ot' devices hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings,'Figure 1 is a side elevation of a Remington No. 2 typewriting machine embodying my improvements. Fig. 2 is a rear elevation of the same. Fig. 3 is a perspective View of the means for attaching the line-locking device to the springdrum, the several parts of said means being separated in order to more clearly exhibit the detail construction of each part. Fig. 4 is a 'detail side elevation, partly in section, of the.

line looking and unlocking devices, looking to the carriage and hinged on the carriage guide-rod 7, 8 the two feed-dogs, 9 the escape` ment-feed-dog rocker or holder, pivoted at 10 in a depending supplemental frame 11, 12 laterally-extending arms from said dog rocker or holder, and 13 connecting-wires extending therefrom to the universal bar 14, arranged below the key-levers, all in the manner customary in said Remington No. 2 machine.

The carriage 3 is connected to the usual spring drum, case, scroll, or the like 15 by means of a strap, band, or belt 16.

Attached by screws 17 to the supplemental frame 1l or formed integral therewith is a bracket 18, which hangs below said frame and which supports an inwardly or forwardly projecting xed pin or stud 19. 20 is an arm or lever formedor provided with a hollow boss or hub 2l, which is mounted upon said pin or projection, so as to be capable ot' a vibratory motion. At the inner end of said boss or hub is secured or formed an upright arm 22, which IOO at its upper free end is cut away or notched, as at 23, to form two lugs or projections 24 and 25. Projecting rearwardly from saidV arm 23 is a pin 26,- with Iiattened sides, which is engaged by a flat spring 27, formed, preferably, Y

with a bend or recess 28, which is attached at one end to an offset from the bracket 18.

y The dog-holder or spacing-rocker 9 is formed or provided at near the free end of its horizontal arm or member with'a depending proj ection 29, which is adapted to cooperate with the lugs 24 and 25 on the rocking arm 22 in a manner to lock the printing mechanism, as will hereinafter more fully appear.

The free outer end of the vibratory arm or lever 2O is formed or provided with a fork, the arms or prongs of which are numbered 30 and 3l.

A curved plate 32 is attached to the springdrum by screws 33, which pass through perforations in the ears 34 at the ends of said plate. Lengthwise of the plate 32 is formed a slot 35, through which passes a screw 36, Whose threaded end engages a tapped holein the block or piece 37, preferably flanged, as at 33, to keep it in position upon said plate. Extending rearwardly from said block or piece is a lug or projection 39, which is adapted to act on both the arms 30 and 31 of the fork and vibrate the lever 2O in opposite directions according to the direction of rotation of the spring-drum to which said lug or projectionA is attached. By reason of the slot 35 the said lug or projection may be adjusted'to actuate the lever at different times, it being only necessary to slightly loosen the screw 36 to enable the block or piece to be slid to any desired locality within the range of the slot and then to retighten the screw to clamp the block again in its new position. A suitable scale or set of graduations may be provided to facilitate the adjustment.

In the forward movement of the carriage, or from right to left, the spring-drum rotates in the direction of the arrow thereat at Fig. 2, and hence the lug or projection 39 travels in the same direction. Vhen said lug or projection contacts with the arm 30, the lever 2O is vibrated upwardly thereby about the pivot 19, and the arm 22, being attached to or forming part of saidl lever, is caused to vibrate toward the right (considered from the front of the machine) until' the lug 24 is brought into allnement with 'the lug 29 of the spacingrocker. When this occurs, the vibration of the spacing-rocker is prevented, and hence the escapement mechanism and the printing mechanism are locked.

At Fig. 2 the actuating-lever 20 and the spacing-rocker-intercepting lugs 24 and 25, controlled thereby, are shown in their normal or unused position, and the traveling lug or contact 39 is shown as just entering the space between the prongs of the fork at the free end of said lever, which is maintained in its shown position by the pressure of the spring 27 on the pin 26. When the lug 39 strikes the inner curved edge-of the prong 30, the lever 2O partakes of the motion of said lug, and in the construction or arrangement shown When the said lug and the said prong have traveled together for about four or five steps or letter-spaces of the carriage the intercepting-lug 24 has been carried over to the vertical position shown at Fig. 4, immediately under the continuously-vibrated lug 29 on the spacing-rocker, and during this travel of said lug 24 the pin 26 has also traveled from the position shown at Fig. 2 to that shown at Fig. 4, where it has entered the depression in the spring, which may thereby more firmly hold the rocking parts .in their locking position. When the lugs 24 and 29 are in register, as shown at Fig. 4, the space-bar or universal bar 14 cannot be depressed or actuated by the key-levers 4, and hence said key-levers, as well as the space-dogs, are locked or prevented from performing their usual functions. Thus not only is the step-by-step feed of the carriage arrested, but the type-bars are prevented from reaching the platen.

As it is often desired to add one or more letters to a word after the line has been locked or to add a punctuation-mark or the like, I have provided means for unlocking the locking mechanism for this purpose and also means for automatically relocking the same after a predetermined number of additional characters have been written.

The lever 2O is formed with a beveled or cam surface 40 below its pivot, and on a rocking rod 41, horizontally arranged in suitable bearings, is formed or provided a pin or projection 42, which normally stands below and out of contact with said inclined or cam surface 40 g but when said rod 41 is rocked the pin or projection 42 is lifted into contact with said cam-surface 40 and wedges or moves the lever 2O upwardly from the position shown in full lines at Fig. 4 to that shown in dotted lines at said figure. This movement or action simultaneously effects a movement of the lug 24 from the full-line locking position to the dotted-line position at Fig. 4, thus unlocking or releasing the spacing mechanism and bringing the notch or cut-away 23 into alinement with the lug 29 on the spacing-rocker, whereby the lug 29 is free to vibrate under the action of the key-levers for a predetermined number of spaces. When these shall have been utilized, the lug 25 will be forced over under the lug 29, and the spacing mechanism will be again arrested.

If the locking-lever 2O be released when the lug 39 is in the position shown at Fig. 4, its prong 30 will rise to the position shown by the dotted lines, and hence the said lug 39 must travel the distance between its present position and the dotted-line position of the prong before it can again contact with said prong, and during this travel of the lug 39, which may be a distance of five or six letter-spaces, more or less, the lug 29 is vibrated in and out of the slot or cut-away 23 during the printing IOO IOS

IIO

of the additional characters; but when the lug 39 again reaches the prong 30 and moves it the lug 25 is carried over into line with the projection 29, and the spacing and printing mechanisms are again locked.

For the purpose of conveniently unlocking the line-locking mechanism when it has irst been locked by the lug 24 I have provided a key-lever 43, extending out'to the keyboard and connected to the rock-shaft 41 by a link 44and a rocker-arm 45, the fulcrum of said key-lever being at 46 and a returning-spring for said lever being provided at 47. Hence When the head or button of the key-lever 43 is depressed the link and the rocker-arm are pulled down, the rock-shaft is oscillated, and the pin or projection 42 is swung up to engage with the lever 2O and move it and its lug-carrying arm 22, as before described.

After the line has been locked either once or twice, as may be desired, the carriage may be returned to the right for the beginning of a newline, and during such return movement the springdrum of course rotates in the opposite direction, and the lu g 39, traveling therewith, strikes the prong 3l of the lever 2O and vibrates it and the arm 22 back to their normal positions, as shown at Fig. 2.

It will be observed from the foregoing that when the movement of the spacingrocker is prevented by either the lug 24 or the lug 25 the spring-drum is incapable of feeding the carriage step by step, as this action can take place only when the spacing-rocker is unobstructed and the dogs are free to alternately engage the rack. I The locking mechanism, however, should be of such character and construction as that the paper-carriage may be run swiftly from right to left for the full ex-` tent of its travel when the carriage-release key is manipulated or when the rack `and dogs are thrown out of engagement Without liability of breakage or derangement of any of the parts or the buckling or casting off of the strap, band, or belt. If the line-locking mechanism should be set or adjusted at, say, 40 on the scale and it should be attempted to run the carriage down to the end of its travel-say at on the scalevby means of the carriage-release key, it will be observed that if the springdrum or the locking mechanism should not automatically7 unlock or release as soon as the carriage passes 40 on the scale (positive margin-stop being disregarded) 'the belt or band would leave the drum and buckle or bulge and be liable to breakage if made of thin steel, and that other breakages or derangement would be liable to ensue under the circumstance mentioned. To

obviate this difficulty, I have so constructed my linelocking mechanism that if the carriage be run past the locking-point under the action of the carriage-release key the linelocking mechanism is at once automatically unlocked and the spring-drum is rendered free to continue its rotative movement to the fullest extent. This is accomplished bythe tent under the action ofthe carriagespring and without liability of breakage, strain, or

derangement of any of the parts.

During the exit of the lug 39 from the opening or cutaway 48, as just explained, owing to the prolongation of the prong or branch 30 the lever 2O and arm 22 are vibrated, and the lug'25 is thrown over to the right (considered from the front of the machine) beyond the plane of the lug 29, so that at the same time the line-loc`kin g mechanism is wholly released;

but this latter feature may be omitted in so far as the feature of the releasement of the spring-drum is concerned, since it is not of specialmoment that the line-lock lugs be thrown out of engagement during the rundown of the carriage, as before explained.

When the lugt) has been carried out of engagement with the pronged lever 20, as just described, said lever is held by the spring 27 in proper position for the said lug to again enter through the opening 48 on the return movement of-the carriage and the reverse rotation of the drum, and if the carriage be moved back far enough the said lug will strike the prong or branch 3l,which is slightly elongated, so as to insure the return of the line-locking lugs 24 and 25 back to their normal positions. (Shown at Fig. 2.)

The carriage-release key is of the usual form found on the Remington No. 2 machine and is designated by the numeral 49. The rear bent end of this key bears upon the forwardly-projecting arm 50, attached to the rack, whereby when the key-head is pressed down the rack is lifted from the dogs and the carriage is free to run down toward the left under the action of the carriage-mainspring. If when the locking-lugs have been brought back to their normal positions the carriage has not been fully returned to its start-ingpoint, the lug 39, during the reverse'turning of the drum, again passes out of the space 48 and travels away from the forked lever until the carriage is stopped; but as the carriage feeds down step by step and the spring-drum turns in the opposite direction the said lug again enters through said lspace and at the predetermined time comes into contact with the fork or branch 30 to arrest the printing and spacing mechanisms.

To prevent the lever 2O and the arm 22 from dropping accidentally from the position shown at Fig. 2, the prong is provided with a stop-pin 51, which is engaged by the pin 26 on the arm 22.

Althoughl have shown my improvements as embodied in a Remington No. 2 machine, it will be understood that they may be used IOO IIO
